BIOS模块在计算机安全系统中的应用研究

Research on the application of BIOS module in computer security system

随着计算机网络化已经在各行各业中得到迅猛发展,网络信息安全越来越受到广大用户的关注,从整体网络化的信息保密到单台计算机的安全与通讯保密已然成为了研究重点。目前,计算机的单机信息保密方面的研究已经初见成效,大致可分为三方面的重点研究:数据完整与保密研究、系统完整性与可信度研究、服务拒绝研究。提出一种基于BIOS模块的计算机底层输入输出安全子系统的设计方案,利用密码学提供的信息摘要、身份识别和数据加密等手段,提供计算机系统的完整性合法性检测,用户身份识别和硬盘数据保护,实现对计算机单机的安全服务。

With the development of computer network has been the rapid development of network information security in all walks of life, more and more attention by the majority of users, from the whole network information security to the security and confidentiality of communications of one computer has become a research focus. At present, the research on single computer information security has produced results,can be divided into three aspects： the research focuses on the data integrity and confidentiality to the integrity and credibility of system research, research and service. According to the above research put forward a design scheme of BIOS module of the bottom of the computer input and output security system based on the information provided by the use of cryptography, identity identification and data encryption and other means to provide integrity checking the validity of the computer system, the user identification and hard disk data protection, security services on single computers.
